Leases [Abstract] |
Lessee, Leases [Policy Text Block] | The company has updated its leasing policy since the issuance of its 2018 Annual Report as a result of the adoption of ASU No. 2016-02, Leases (Topic 842) in the first quarter 2019. See Notes 2 and 11 for additional information. See Note 1, "Summary of Significant Accounting Policies," in the 2018 Annual Report for more information on Historical DuPont's other significant accounting policies. Leases The company determines whether an arrangement is a lease at the inception of the arrangement based on the terms and conditions in the contract. A contract contains a lease if there is an identified asset and the company has the right to control the asset. Operating lease right-of-use ("ROU") assets are included in other assets on the company’s Consolidated Balance Sheets. Operating lease liabilities are included in accrued and other current liabilities and other noncurrent obligations on the company’s Consolidated Balance Sheets. Finance lease assets are included in property, plant and equipment on the company’s Consolidated Balance Sheets. Finance lease liabilities are included in short-term borrowings and finance lease obligations and long-term debt on the company’s Consolidated Balance Sheets. Operating lease ROU assets represent the company’s right to use an underlying asset for the lease term and lease liabilities represent the company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As most of the company’s leases do not provide the lessor's implicit rate, the company uses its incremental borrowing rate at the commencement date in determining the present value of lease payments. Lease terms include options to extend the lease when it is reasonably certain those options will be exercised. Leases with an initial term of 12 months or less are not recorded on the balance sheet. The company recognizes lease expense for these leases on a straight-line basis over the lease term. The company has lease agreements with lease and non-lease components, which are accounted for as a single lease component for all asset classes. In the Consolidated Statements of Operations, lease expense for operating lease payments is recognized on a straight-line basis over the lease term. For finance leases, interest expense is recognized on the lease liability and the ROU asset is amortized over the lease term. The company has operating and finance leases for real estate, airplanes, railcars, fleet, certain machinery and equipment, and information technology assets. The company’s leases have remaining lease terms of 1 year to 50 years. For purposes of calculating operating lease liabilities, lease terms may be deemed to include options to extend the lease when it is reasonably certain that the company will exercise that option. Some leasing arrangements require variable payments that are dependent on usage, output, or may vary for other reasons, such as insurance and tax payments.
